Travere Therapeutics to Present New FILSPARI® (sparsentan) Data at the 62nd ERA Congress
Data from SPARTACUS and PROTECT OLE to show significant proteinuria reduction when replacing RASi with FILSPARI and when FILSPARI is used in combination with SGLT2i New mechanistic data to show FILSPARI protects against IgA deposition in the kidney SAN DIEGO, June 03, 2025--(BUSINESS WIRE)--Travere Therapeutics, Inc., (Nasdaq: TVTX) today announced that the Company will present seven abstracts at the upcoming European Renal Association (ERA) Congress in Vienna, Austria, June 4-7. Presentations will include new data on the use of FILSPARI in IgA nephropathy (IgAN) from the Phase 2 SPARTACUS Study which demonstrated that FILSPARI provided clinically meaningful benefits in adults with IgAN who replaced their renin-angiotensin system inhibitor (RASi) with FILSPARI while receiving stable sodium-glucose cotransporter-2 inhibitor (SGLT2i) therapy. A presentation on results from the open label extension (OLE) of the Phase 3 PROTECT Study will show that patients previously treated with maximum labeled irbesartan experienced significant proteinuria reduction after switching to FILSPARI in the study. In a preclinical model of IgAN, FILSPARI protected from mesangial deposition of IgA, suggesting a potential role of endothelin-1 and angiotensin II as modulators of disease activity in IgAN. Data from the gddY mouse model of IgAN will offer new insight into the pathogenesis of IgAN as a tissue-specific autoimmune disease. In focal segmental glomerulosclerosis (FSGS), the Company will share a data analysis from the Phase 3 DUPLEX Study showing that partial and complete proteinuria remission were achieved earlier and more frequently with FILSPARI than irbesartan. The Company will also present preclinical data in an animal model of immune-mediated FSGS showing that optimized dual endothelin and angiotensin blockade with FILSPARI helps protect the integrity of the glomerular filtration barrier, reducing glomerular permeability and lowering albuminuria. "The breadth of data we're presenting underscores our confidence in the role FILSPARI can serve as foundational therapy for rare kidney diseases," said Jula Inrig, M.D., chief medical officer of Travere Therapeutics. "These findings provide further evidence that FILSPARI can decrease the risk of IgAN disease progression. We are deeply committed to advancing research and delivering innovative therapies that can make a meaningful difference for people living with IgAN and FSGS."

The deposits of IgA cause a breakdown of the normal filtering mechanisms in the kidney, leading to blood in the urine (hematuria), protein in the urine (proteinuria) and a progressive loss of kidney function. Other symptoms of IgAN may include swelling (edema) and high blood pressure. IgAN is the most common type of primary glomerulonephritis worldwide and a leading cause of kidney failure due to glomerular disease. IgAN is estimated to affect up to 150,000 people in the U.S. and is one of the most common glomerular diseases in Europe and Japan. About Focal Segmental Glomerulosclerosis Focal segmental glomerulosclerosis (FSGS) is a rare proteinuric kidney disorder in both children and adults that is estimated to affect more than 40,000 patients in the U.S. with similar prevalence in Europe. The disorder is defined by progressive scarring of the kidney and often leads to kidney failure. FSGS is characterized by proteinuria, where protein leaks into the urine due to a breakdown of the normal filtration mechanism in the kidney. Once in the urine, protein is considered to be toxic to other parts of the kidney, especially the tubules, and is believed to contribute to further disease progression. Other common symptoms include swelling in parts of the body, known as edema, as well as low blood albumin levels, abnormal lipid profiles and hypertension. Sparsentan is not approved for use in FSGS. There is currently no approved pharmacologic indicated for the treatment of FSGS. About Travere Therapeutics At Travere Therapeutics, we are in rare for life.

IMPORTANT SAFETY INFORMATION BOXED WARNING: HEPATOTOXICITY AND EMBRYO-FETAL TOXICITY Because of the risks of hepatotoxicity and birth defects, FILSPARI is available only through a restricted program called the FILSPARI REMS. Under the FILSPARI REMS, prescribers, patients and pharmacies must enroll in the program. Hepatotoxicity Some Endothelin Receptor Antagonists (ERAs) have caused elevations of aminotransferases, hepatotoxicity, and liver failure. In clinical studies, elevations in aminotransferases (ALT or AST) of at least 3-times the Upper Limit of Normal (ULN) have been observed in up to 3.5% of FILSPARI-treated patients, including cases confirmed with rechallenge. Measure transaminases and bilirubin before initiating treatment and monthly for the first 12 months, and then every 3 months during treatment. Interrupt treatment and closely monitor patients who develop aminotransferase elevations more than 3x ULN. FILSPARI should generally be avoided in patients with elevated aminotransferases (>3x ULN) at baseline because monitoring for hepatotoxicity may be more difficult and these patients may be at increased risk for serious hepatotoxicity. Embryo-Fetal Toxicity FILSPARI can cause major birth defects if used by pregnant patients based on animal data. Therefore, pregnancy testing is required before the initiation of treatment, during treatment and one month after discontinuation of treatment with FILSPARI. Patients who can become pregnant must use effective contraception before the initiation of treatment, during treatment, and for one month after discontinuation of treatment with FILSPARI. Contraindications FILSPARI is contraindicated in patients who are pregnant. Do not coadminister FILSPARI with angiotensin receptor blockers (ARBs), ERAs, or aliskiren. Warnings and Precautions Hepatotoxicity: Elevations in ALT or AST of at least 3-fold ULN have been observed in up to 3.5% of FILSPARI-treated patients, including cases confirmed with rechallenge. While no concurrent elevations in bilirubin >2-times ULN or cases of liver failure were observed in FILSPARI-treated patients, some ERAs have caused elevations of aminotransferases, hepatotoxicity, and liver failure. To reduce the risk of potential serious hepatotoxicity, measure serum aminotransferase levels and total bilirubin prior to initiation of treatment and monthly for the first 12 months, then every 3 months during treatment. Advise patients with symptoms suggesting hepatotoxicity (nausea, vomiting, right upper quadrant pain, fatigue, anorexia, jaundice, dark urine, fever, or itching) to immediately stop treatment with FILSPARI and seek medical attention. If aminotransferase levels are abnormal at any time during treatment, interrupt FILSPARI and monitor as recommended. Consider re-initiation of FILSPARI only when hepatic enzyme levels and bilirubin return to pretreatment values and only in patients who have not experienced clinical symptoms of hepatotoxicity. Avoid initiation of FILSPARI in patients with elevated aminotransferases (>3x ULN) prior to drug initiation because monitoring hepatotoxicity in these patients may be more difficult and these patients may be at increased risk for serious hepatotoxicity. Embryo-Fetal Toxicity: FILSPARI can cause fetal harm when administered to a pregnant patient and is contraindicated during pregnancy. Advise patients who can become pregnant of the potential risk to a fetus. Obtain a pregnancy test prior to initiation of treatment with FILSPARI, monthly during treatment, and one month after discontinuation of treatment. Advise patients who can become pregnant to use effective contraception prior to initiation of treatment, during treatment, and for one month after discontinuation of treatment with FILSPARI. FILSPARI REMS: Due to the risk of hepatotoxicity and embryo-fetal toxicity, FILSPARI is available only through a restricted program called the FILSPARI REMS. Prescribers, patients, and pharmacies must be enrolled in the REMS program and comply with all requirements ( Hypotension: Hypotension has been observed in patients treated with ARBs and ERAs. There was a greater incidence of hypotension-associated adverse events, some serious, including dizziness, in patients treated with FILSPARI compared to irbesartan. In patients at risk for hypotension, consider eliminating or adjusting other antihypertensive medications and maintaining appropriate volume status. If hypotension develops, despite elimination or reduction of other antihypertensive medications, consider a dose reduction or dose interruption of FILSPARI. A transient hypotensive response is not a contraindication to further dosing of FILSPARI, which can be given once blood pressure has stabilized. Acute Kidney Injury: Monitor kidney function periodically. Drugs that inhibit the renin-angiotensin system (RAS) can cause kidney injury. Patients whose kidney function may depend in part on the activity of the RAS (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion) may be at particular risk of developing acute kidney injury on FILSPARI. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in kidney function while on FILSPARI. Hyperkalemia: Monitor serum potassium periodically and treat appropriately. Patients with advanced kidney disease, taking concomitant potassium-increasing drugs (e.g., potassium supplements, potassium-sparing diuretics), or using potassium-containing salt substitutes are at increased risk for developing hyperkalemia. Dosage reduction or discontinuation of FILSPARI may be required. Fluid Retention: Fluid retention may occur with ERAs, and has been observed in clinical studies with FILSPARI. FILSPARI has not been evaluated in patients with heart failure. If clinically significant fluid retention develops, evaluate the patient to determine the cause and the potential need to initiate or modify the dose of diuretic treatment then consider modifying the dose of FILSPARI. Most common adverse reactions The most common adverse reactions (≥5%) are hyperkalemia, hypotension (including orthostatic hypotension), peripheral edema, dizziness, anemia, and acute kidney injury. Drug interactions Renin-Angiotensin System (RAS) Inhibitors and ERAs: Do not coadminister FILSPARI with ARBs, ERAs, or aliskiren due to increased risks of hypotension, syncope, hyperkalemia, and changes in renal function (including acute renal failure). Strong and Moderate CYP3A Inhibitors: Avoid concomitant use of FILSPARI with strong CYP3A inhibitors. If a strong CYP3A inhibitor cannot be avoided, interrupt FILSPARI treatment. When resuming treatment with FILSPARI, consider dose titration. Monitor blood pressure, serum potassium, edema, and kidney function regularly when used concomitantly with moderate CYP3A inhibitors. Concomitant use with a strong CYP3A inhibitor increases sparsentan exposure which may increase the risk of FILSPARI adverse reactions. Strong CYP3A Inducers: Avoid concomitant use with a strong CYP3A inducer. Concomitant use with a strong CYP3A inducer decreases sparsentan exposure which may reduce FILSPARI efficacy. Antacids and Acid Reducing Agents: Administer FILSPARI 2 hours before or after administration of antacids. Avoid concomitant use of acid reducing agents (histamine H2 receptor antagonist and PPI proton pump inhibitor) with FILSPARI. Sparsentan exhibits pH-dependent solubility. Antacids or acid reducing agents may decrease sparsentan exposure which may reduce FILSPARI efficacy. Non-Steroidal Anti-Inflammatory Agents (NSAIDs), Including Selective Cyclooxygenase-2 (COX-2) Inhibitors: Monitor for signs of worsening renal function with concomitant use with NSAIDs (including selective COX-2 inhibitors). In patients with volume depletion (including those on diuretic therapy) or with impaired kidney function, concomitant use of NSAIDs (including selective COX-2 inhibitors) with drugs that antagonize the angiotensin II receptor may result in deterioration of kidney function, including possible kidney failure. CYP2B6, 2C9, and 2C19 Substrates: Monitor for efficacy of concurrently administered CYP2B6, 2C9, and 2C19 substrates and consider dosage adjustment in accordance with the Prescribing Information. Sparsentan decreases exposure of these substrates, which may reduce efficacy related to these substrates. P-gp and BCRP Substrates: Avoid concomitant use of sensitive substrates of P-gp and BCRP with FILSPARI. Sparsentan may increase exposure of these transporter substrates, which may increase the risk of adverse reactions related to these substrates. Agents Increasing Serum Potassium: Monitor serum potassium frequently in patients treated with FILSPARI and other agents that increase serum potassium. Concomitant use of FILSPARI with potassium-sparing diuretics, potassium supplements, potassium-containing salt substitutes, or other drugs that raise serum potassium levels may result in hyperkalemia. Please see the full Prescribing Information, including BOXED WARNING, for additional Important Safety Information.

U.K. Funds Geoengineering Experiments as Global Controversy Grows
CLIMATEWIRE | As temperatures fall and sunlight wanes this winter, scientists will gather in the Canadian Arctic with drills and pumps in tow. Their mission: to refreeze the region's melting sea ice. Known as Re-Thickening Arctic Sea Ice, or RASi, the project aims to pump seawater from the ocean and spray it over the top of existing ice floes, where the cold air will freeze it solid. Researchers hope that the process will create a thicker layer of sea ice, helping undo some of the damage caused by rising global temperatures. For now, it's just an experiment — and a relatively small one at that. Over the next three winter seasons, the researchers plan to refreeze areas as large as 1 square kilometer, or 0.38 square miles. Along the way, they'll assess how the project affects the local ecology and the movement of the sea ice — and how long it takes to melt again in the summer.

By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today. The project is one of a handful of geoengineering experiments funded by the British government. UK's Advanced Research and Invention Agency (ARIA) announced on Wednesday that it would invest a total of about $60 million in climate-cooling research, spread among 21 projects. ARIA was established in 2023 to support a variety of research fields, from artificial intelligence to genetic engineering, but its investment in geoengineering studies counts as among its most controversial projects. The discourse has only grown more polarized as new research pushes once-futuristic techno-solutions into the realm of possibility. Research advocates argue that the world is not reducing greenhouse gases fast enough to meet the Paris Agreement's global climate goals. Cutting carbon emissions is still the most important way to address climate change — but as the planet heats up, they argue, scientists should understand the potential pros and cons of climate-cooling technology. But critics worry that too much emphasis on geoengineering could distract world leaders from their efforts to phase out fossil fuels and reduce emissions. Meanwhile, other recent geoengineering experiments have ended amid public criticism, including Harvard University's SCoPEX experiment, a University of Washington cloud-brightening experiment and a sea ice-refreezing project conducted by an organization known as the Arctic Ice Project. An unauthorized experiment in 2022 by the startup Make Sunsets in Baja California, Mexico, resulted in a solar geoengineering ban from the Mexican government. Meanwhile, the world's largest geoengineering conference — the Degrees Global Forum — is set to begin in Cape Town, South Africa, next week. Most of ARIA's new projects involve computer modeling, climate monitoring or social questions related to governance and ethics surrounding geoengineering. Only five projects call for real-life outdoor experiments — but they're easily the most expensive of all the research categories, totaling about $32 million in awarded funds. RASi received the most funding of all projects, at $13 million over the next 42 months. Other experiments on the list include three projects aimed at brightening clouds to reflect more sunlight away from the Earth. A fifth experiment focuses on stratospheric aerosol injection, a strategy that would spray reflective particles into the atmosphere to directly beam sunlight back into space. The project would load up various kinds of mineral dust into weather balloons to test how they interact with the air at high altitudes without directly releasing them into the sky. All outdoor experiments will undergo legal and environmental assessments in advance, said Mark Symes, an ARIA program director, in an email. And none of them will release toxic materials or deliberately set out to cool the climate, he said. The announcement garnered both concern and support from organizations involved in global conversations around geoengineering. 'The UK Government risks triggering a costly, dangerous, and distracting race to develop technologies that should never be used,' said Mary Church, a geoengineering campaign manager with the nonprofit Center for International Environmental Law, in a statement. 'Even experimenting with these technologies could further destabilise an already tense geopolitical context.' The country should instead focus on phasing out fossil fuels, she added, suggesting that even small-scale experiments could become a 'slippery slope' on the way to larger geoengineering deployments. But Kelly Wanser, executive director of the nonprofit SilverLining, said in a statement that she was 'heartened to see our friends at ARIA and the government in the UK recognize the need for responsible scientific research on potential interventions in the Earth system.' SilverLining advocates for geoengineering research. Symes emphasized that cutting carbon emissions should remain the world's priority when it comes to addressing climate change. Still, he added, more research is 'essential' for informed global decision-making around potential climate interventions. 'ARIA's programme is focused on generating fundamental scientific evidence about whether any proposed climate cooling approaches could ever be safe or feasible — or whether they should be ruled out entirely,' he said in an email.
